In order to release the connection between the navigation device 200 and the connection station, for example, a button on the navigation device _ can be pressed (this is merely an example, and other known alternatives for disconnecting the connection station do not deviate from the application) The scope of the case). In at least the specific embodiment, the method of the present application includes determining the navigation device to enter-way during the travel route of the navigation device 200; and after deciding that the navigation device 200 enters the track, in the decision Talk about 125649.doc -18- 200829877 The tunnel system is longer than a first critical distance, — a ^ 蛤 扣 令 预定 预定 预定 预定 预定

One of the outlets of the second critical distance inner wheel Φ β > X and the navigation command is intended to output at least one of the channels in the track, and the output is output to a user of the navigation device 200 in the track ^ ¥航 instruction to travel along the route. In the case of at least one of the present inventions, a navigation device 200 package

The processing benefit 210 is used to 'determine the navigation device 200 to enter the track during one of the navigation devices 2'; and an output device 241 for processing after determining that the navigation device 200 enters the tunnel The controller 21 determines that the channel is longer than the -th critical distance, the navigation command is intended to be output within a second critical distance of one of the exits of the tunnel, and the navigation command is intended to be at least one of the tracks The user receives a navigation command to the user of the navigation device in the tunnel to travel along the travel route. With respect to at least one embodiment, the inventors have discovered that triggering for outputting instructions that can be used to navigate a travel route may be blocked in certain known areas or under certain conditions. Thus, it has been found that it is more beneficial for the user to allow early output of navigation instructions when such areas or conditions are expected or detected. An exemplary embodiment of the present application is illustrated in Figure 5A. As shown in Fig. 5A, for example, in step S2, the processor 21 of the navigation device 200 determines whether the navigation device 200 has entered a track. For example, a processor 21 最初 initially receives an input or selected destination location from a user of the navigation device 200. From then on, a route can be calculated in a known manner based on the map information stored in the memory 230, the destination, and the GPS location of one of the navigation devices 200. Before the calculation of such a route, the map information in the memory 230 can be checked for the tunnel and can be used for each tunnel (or the processor 2i 地图 in the map data used in determining the route) An otherwise identified tunnel) is used to set a tunnel marker or flag such that, during route calculation, for example, the processor 210 of the navigation device 200 can identify whether a user will be traveling on a include-and-route route. For example, it is customary to mark a point or node on a map f, so for a tunnel, on the map information, a "mark" or another standard line between the two nodes of the tunnel can be marked. The node is usually marked. At the joint, therefore, a full piece of map information between the two joints can be marked as a tunnel. Thus, during travel along the route, the processor 2 can determine the navigation device 2 based on the marker/flag settings. Whether one of the users is traveling along a navigation route having a tunnel. Thereafter, in steps S4, S6, S7 and S, it is possible, for example, by the processor 21 to determine whether at least one other condition has been met. The order of steps S4, S6, S7 and S8 is not important, since the processor 21〇 can determine the conditions of the various conditions in any order. In step S4, it can be determined, for example, by the processor 21〇 whether the tunnel is longer than a critical value, , x" distance. For example, if the tunnel is only a short distance, it is likely that no command output will be required while the navigation device 200 is still within the tunnel. Such a critical distance can be set within the map information such that, for example, only when the tunnel is longer than a certain critical distance. Alternatively, a tunnel flag can be set for all tunnels, and then the processor 21〇 compares the length to the limit value during navigation. Such a critical distance may be, for example, two inches. It should be noted that this step S4 is selected when at least one of steps S6 and S8 is utilized. Thus, if the processor 21 determines that the tunnel is longer than a critical "χ" from 125649.doc -20-200829877, then at step s10, the processor 210 will be within the tunnel). The round-out command (for example, may be performed in step S6, for example, by a processor 21 a predetermined threshold after the -way exit, y: = aeronautical command whether the processor 210 knows the predetermined output is different. For example , Bu Jingling's time and usually its /

- Receive a Gps signal for a specific map location to output - an instruction. Two can be done in a known way. Thus, if the processor knows that the instruction is intended to be output within one inch of, for example, the egress exit (measured from or after it), and the processor 21G knows that the navigational vibrating (four) is currently located in the lane, If one (10) signal is lost, the (10) signal cannot be recovered in time and the processor 21 of the navigation device 2 cannot output the command at the appropriate time. Therefore, if the 'navigation command function is output in the threshold ^ (for example, a tunnel exit - English), then at step, the processor 210 will instruct the output of the fingerprint in the channel to make a sufficient warning. The user appears after the tunnel - the upcoming turn, merger, entry - highway, etc. It should be noted that this step is selected when at least one of the steps S4AS8 is utilized. Finally, at step S8, a navigation command can be determined, for example, by the processor 21 to be scheduled to be output within the tunnel. For example, in certain tunnels of such tunnels, such as Brussel, Belgium, joints may be included in the tunnel. In this case, at step sio, such instructions need to be output to the user within the tunnel itself. This condition may be detected by processor 21 in a manner similar to that set forth above in steps S4 and S6 to provide an output at step sio when the condition is met. It should be noted that this step S8 is optional when utilizing at least one of steps 84649 and doc - 21 - 200829877 of steps 84 and 86. Thus, in a method according to an exemplary embodiment of the present application, during the route of one of the navigation devices 2, the processor 21 may determine the navigation device as a follower in step S2. And after deciding that the navigation device 2〇〇 enters the accompaniment, the processing is determined by the step (4) in the step (4) with the line length: - the first limit value, and in step 86, the navigation command is scheduled to be one of the exits of the tunnel. The second critical distance is output and/or in the step "The navigation command is scheduled to be output to "less" in the track, the navigation command may be rotated in the (four) track in step S10' to travel along the route. The step S10 outputting the navigation command may include visually rotating the navigation command on, for example, one of the navigation device and the integrated input and display device 29G and/or, for example, via a speaker in the navigation device 2 At least one of the navigation commands is audibly outputted. Figure 5B illustrates another exemplary embodiment of the present application. When the step is followed by (four) _ travel destination 'by (for example) processor Chuan initial: navigation device 200 Booking route For example, once a row destination is selected or entered, a route can be determined in a known manner by indicating a receiving (four) signal of the current location, storing map information, and receiving the destination. And then, for example, the processor 2i0 may determine, in step S14, whether the determined special route of the decision will be a tactical θ including a tooth over-track. Similarly, in determining the route % ' The system is generally identified within the body 230 and can then be detected, for example, by the processor 210. If the route does not involve passing through one, the shot can be taken in step SJ6 and the wheel in the -normal manner I25649 .doc -22. 200829877 These instructions, of course, take into account any other reasons for outputting or not outputting the instructions. If the answer to step S14 is yes, then the processor 21 may, for example, determine at step S18; Whether the device 2〇〇 enters the tunnel in a manner somewhat similar to that proposed, for example, in Figure 5A. The subsequent steps S2, S22, S23, S24, and S26 of Figure 5B may be preceded by the individual steps S4 of Figure 5A. The steps S20, S22, S24, and S24 are not important, and the processor 21〇 can determine the conditions of various conditions in any order. 5A and 5B, determining that the navigation device 200 enters the tunnel may further include the following steps: • The processor 210 determines that a GPS nickname (usually not indicating the current location of the navigation device 2) cannot be received for a period of time exceeding a limit value For example, the processor 21 may first determine whether the GPS signal has not been received for a period of time (eg, three seconds), and if so, the processor 210 may then determine the navigation device 2 0 in the manner previously described. Whether to enter the channel. In this example, in step S7 of FIG. 5A or step S23 of FIG. 5B, it may be determined, for example, by the processor 210 whether a navigation command is intended to be output within one of the navigation device 200's estimated current position "z" Thus, if the processor 210 determines that a GPS signal cannot be received for a period of time exceeding a defined value (eg, three seconds), the processor 210 may then determine one of the steps S7 of FIG. 5A or step S23 of FIG. 5B. Whether the command is intended to be output within a critical "z" distance of one of the navigation devices 200 estimating the current position (note that the processor 200 can be based on a last known GPS position signal received, one of the most 125649.doc -23-200829877

After the known parent tool speed and the time elapsed from receiving a valid G ps signal determines the current position of one of the vehicles in which the navigation device is located, the right answer is yes, then in step S10, the processor 21〇 The output command will be indicated (for example, it may be in the track). The limit value "z" can be, for example, two inches' wherein the command is output when the processor 210 determines that a command is intended to be output within two inches of the current position of the navigation device 200. It should be noted that when at least one of steps S4, 86 and 88 is utilized, this step 87 or "for the use of k" should be noted that when the combination decision is continued for a critical time period, a GPS signal is missing to utilize 87 or § 23, respectively. Steps S4, 86 and 88 or any of gamma, S22 and S24 are selected. It should be further noted that the processor 210 determines that the failure to receive a GPS signal may include the __ time at which the cache navigation device 200 receives the -GPS signal, and counts the time after receiving the -GPS signal and compares the count with the limit value to determine Whether the limit has been exceeded. For example, this step can be included in any of the Figures 5a and 5B. Regarding the various distance limit values described in steps S4 and S6, the limit values may be the same or different from the month b or may be further different. For example, the distance limit value in step S4 of FIG. 5a and S20 in FIG. 5B may be a relatively longer distance than one of the step limit values set in step 5A of FIG. 5A and S24 of FIG. 5B, since it may be expected The navigation command is outputted in a tunnel only when the tunnel distance or length is large, and it is further desirable to be in the tunnel when another or next command is scheduled to be output to the user only within a short distance of the tunnel exit. Output navigation instructions. It should be noted that one of the applications has been described with respect to the method of the present application. 125649.doc -24· 200829877

Aspects of the foregoing aspects of the embodiments. However, at least one embodiment of the present application is directed to a navigation device that includes a processor 210 for determining that the navigation device 200 enters a tunnel during one of the navigation devices 200; and an output The device 241 is configured to determine, after the processor enters the navigation device, 200 into the (four) track, the processor 21 determines that the channel is longer than a [critical distance, - the navigation command is in the (four) way - the second threshold of the exit The in-range output and the navigation command are output to the user of the navigation device in the tunnel to perform a navigation command along at least one of the in-track outputs. Such a processor 210 can be enabled in the (4)-selection option to enable the option and/or enable the display. Such a navigation device 200 can be used to perform various aspects of the method described with respect to Figures 53 as will become apparent to those skilled in the art. Therefore, further explanation is omitted for the sake of brevity. In at least the specific embodiment of the present application, the method includes determining the time during which the navigation device fan is receiving a GPS signal during a navigation device 200 traveling along the -travel route and determining that the navigation device 2 continues for one time. The time during which the _GPS signal was not received during the time limit exceeded. The method further includes 'outputting a navigation command to the user of the navigation device' to travel along the route when the GPS device is not received for a period of time during which the navigation device 2 决定 continues to exceed a defined value. In at least the specific embodiment of the present application, a navigation device 2 includes a processor 210 for delaying the reception of a signal during a navigation device 2 traversing a travel route And a time period for determining that the navigation device 200 does not receive a GPS signal during a time period in which the navigation device 200 lasts for more than a limit value 125649.doc -25-200829877. _舲^ ^ The UM system 241 is further arranged to not receive a GPS signal during the period when the processor 210 determines that the navigation device 2 is less than the limit value. The navigation command is directed to a user of the guide 200 to travel along the route. FIG. 6A illustrates an exemplary embodiment of the present application. In this exemplary embodiment, in step S30, the processor 3 initially determines by the processor 210 (^: no one (four) signal has been received. If so, the system goes back to repeat the step (four) 'assumed in-navigation If the decision is made that the navigation device 2〇0 has not received the signal, the program moves to step S32, where the processor 21() determines (for example) whether it exceeds one. The critical time, that is, whether the navigation device 200 has not received the GPS signal during the time period of more than one 〇Λ limit value. If the step 2 determines that the navigation device 200 continues to exceed the limit value, the GPS is not received. After the signal, the processor 21 moves to s34, and the navigation device-output device 241 outputs a navigation command to a user of the navigation device 200. It should be understood that the steps and the steps may be, for example, by a navigation device. Executing the navigation command by an output device 241 may include, for example, displaying the navigation command by an integrated input and display device 29 of the navigation device and/or (eg, At least one of the navigation instructions is audibly output via a speaker or other audible output device of the navigation device 2GG. Solid 6B illustrates another exemplary embodiment of the present application. In this embodiment, 'deciding whether to receive A GPS signal. If so, the program 125649.doc -26-200829877 moves to step S42, wherein, for example, the GPS signal is stored in the memory 230, thereby storing one of the current positions of the navigation device 2. Once received To the GPS signal, a counter is reset to begin counting at step 844. The program then loops to step S40. - If, for example, processor 210 of navigation device 200 determines that a GPS signal has not been received, then at step S40, A current count may be compared by processor 210 with a defined value (e.g., the neighbor time of step S32 of Figure 6A) at step S46. Thereafter, at step S48, it may be determined, for example, by processor 210 whether the The limit value. If yes, the navigation command may be output in step S52 in a manner somewhat similar to that previously described. If not, the count is updated in step S5 and in step S40 Determining whether to receive the gpS signal. Alternatively, the processor 210 may check a time difference between a current time and a time when a last GPS chirp is received. For example, one of the navigation devices may send a position signal every second. And in this position, a flag can be sent to determine if it is valid. Thereafter, the processor 21 can count the number of unmarked GpS locations instead of receiving a last valid GPS at a current time. The time between the signals is compared for a time. Figure 6C illustrates another alternative embodiment of the present application. Initially, a decision is made at step S60 whether a Gps signal is received. If it is decided to receive a Gps signal, the system loops back to step S6. However, if it is determined that the navigation device 2 has not received a GPS signal, then at step S62, the processor 21 determines, for example, whether one of the 仏 一 GPS 仏 最后 last received a critical time. If not, the program loops back to step S6(). However, if, for example, the processor 21 of the navigation device 2 determines that the navigation device 125649.doc -27- 200829877 4 2〇0 continues to receive a - GPS signal during a time period exceeding a limit value, the program Move to step S64. In step (5), it is determined whether the navigation device 200 is traveling along a part of the route that is adjacent to a known GPS signal. This area may be an identification area that the processor 2 can detect, for example, in a manner similar to that described in the tunnels of Figures 5-8 and 5B, where similar to, for example, a tag, " Identifies " or otherwise marks the -travel line between the two nodes stored. The nodes are usually marked at the junction 'so the entire map information between the two junctions can be marked as a known GPS signal loss area (but tunnels may also occur between nodes such areas may be a tunnel, one A mountain, an underpass, a canyon, or at least one urban high-rise group. Similarly, for example, the known (10) signal loss region can be similar to that described above with respect to the tunnels in Figures 5 and 5b of the present application. The processor 210 may determine, by the processor 21, in step S64, whether the last known GPS position of the navigation device 2 is within a critical distance of φ of the known GPS signal loss region. It is known whether the GPS signal loss area is close to the current position of one of the navigation devices 200. If the answer to step S64 is no, the method proceeds back to step S60. However, if the answer is yes, then at step S66, ie at processor 210 Determining that the navigation device 2 is traveling along a part of the travel route adjacent to a known lost area of the GPS # number, and outputs a navigation command. Since the node is usually marked at the joint, This entire map information between the two junctions can be marked as a known GPS signal loss area. Such areas may be a tunnel, a mountain range, an underground road, a canyon, a city 125649.doc -28 - 200829877 Back to at least one of the group. Similarly, for example, the known GPS signal loss region can be identified in a manner similar to that described above with respect to the tunnels in Figures 5 and 5B of the present application, such that when When the Gps nick is lost during the travel area, the processing state 210 assumes that it is entering a tunnel, a mountain range, an underground road, a canyon, a high-rise building, and the like.

It should be noted that the output navigation command at step S66 typically occurs within the known GPS signal loss region. However, this is not necessarily the case. For example, the command can be output during a critical time period after the GPS signal is lost, e.g., 3 seconds after entering the known GPS signal loss region. However, this may be subject to other parameter constraints, such as whether the command is predetermined to be within a critical distance of one of the exits of the known L-loss region or a critical distance of the navigation device 2 Internal output (note that the processor 200JT determines the vehicle in which the navigation device is located based on the received _ last known (four) position signal, the last known vehicle speed, and the time elapsed since the receipt of the - valid GPS signal - Estimate the current location). In addition, in at least one other specific embodiment of the present application, the processor 2 may determine, for example, that the navigation command is predetermined to be one of the navigation devices 2 to determine the position-critical "z" The distance output is adjusted to adjust the output port of step S66, and in step S62, the processor 2 ι determines that a Gps signal is not received during a time period (for example, three seconds) exceeding the limit value, then the 221G can be followed by Decide whether the instruction is intended to be within a critical "Z" distance of one of the navigation device's estimated current positions. The idea processor may be based on a last known Gps position signal received, a final 125649.doc - 29- 200829877 It is known that the vehicle speed and the elapsed time from receiving a valid GPS signal determine that one of the vehicles in which the navigation device is located estimates the current position. If the answer is yes, then in step S66, the processor 21 Indicates that the instruction is taken out (for example, possibly within the tunnel). The limit value "z" may be, for example, two inches. One of the commands is output when the processor 21 determines that an indication is intended to be output within two inches of the current position of one of the V avionics 200. In any of the foregoing specific embodiments of the application, a navigation command may be adjusted prior to outputting to compensate for a period of time during which the decision not to receive the (3)-8 signal. For example, if a command is scheduled to exit a tunnel Output, and it is known that the instruction is intended to be output at a specific distance from the -export, - highway population, any other specific turn, etc., for example by increasing the distance

After the parameters have been adjusted, the τ-instruction can be output early in the tunnel within the step of, for example, W5a. For example, instead of declaring "turning right after ι〇〇米', the navigation instruction can be 'adjusted' before the output is timed to compensate for the decision not to receive the Gps signal. For example, the instruction can be output as "at 500" After the meter turns right, the navigation device 2 continually updates the position based on the last known Gps position and the last learned command. Because, for example, the location of the GPS that is known after i (ie, the position at which an instruction should be output - the distance traveled (based on the time elapsed between the speed of the fish when the last GPS signal is received) is processed by the processor 210. To complete the navigation command::, for example, 'If the navigation device is in the vehicle that is traveling at 2 / m / sec, then for example, (10) the signal I am missing before the arrival of the next turn, instead of outputting an instruction , 诌明"1 nnn Zhuo Your brother did not turn right after 1000,, if the instruction is provided after 5 (4) after losing the GPS signal, it will be adjusted to the right after 125649.doc -30- 200829877 # f '心It is assumed that the vehicle travels another ι metre within the 5 seconds. It should be noted that the various aspects of the foregoing aspects of the specific embodiments have been described with respect to the method of the present application. At least one embodiment of the present application is directed to a navigation device that includes a processor for determining when the navigation device 200 is traveling along a travel route, determining when the navigation device 200 receives a GPS signal, and Decision The time during which the device 2〇0 continues to receive a GPS signal during the time exceeding the limit value. The output device 241 is stepped in to include during the time when the processor 2H) determines that the navigation device 200 continues to exceed the limit value. Receiving a t5 tiger% outputs a navigation command to one of the navigation device 2's to travel on the route. Such a processor 21 can enable an option and/or a display to be displayed when a selection option is received.
